Monitor System Resources With “Resources”

Today is one of those days when I’d like to introduce you to new software as we learn to monitor system resources with “Resources”. That may not make much sense, but it will! The Resources application is a great option if you want a great way to monitor system resources.

I may do a few articles about monitoring system resources. That’ll be fun.

It’s probably important to mention that many of you will not have this in your default repositories. For those who do, it won’t be in the typical repositories but will exist because your distro ships with Flatpaks enabled.

That’s right. To use this article, you should read a previous article:

Installing Flatpaks In Linux

Once you get Flatpak installed and the FlatHub repository added, you can use a great application known as Resources.

Of course, your desktop distro shipped with a GUI resource monitor and it’s usually fit for purpose. However, this Resources application has a bunch of great features and it is easy to live with. 

Another great thing is that this shouldn’t be a very long article…

Monitor System Resources:

Once Flatpak is installed, you might want to keep your terminal open. Yes, Flatpaks are large – but they have great features, including running in isolation and shipping with all their dependencies.

Most of you can open a terminal by pressing CTRL + ALT + T. If that doesn’t work for you, you’ll have a terminal option in your application menu. It might be under the Administration sub-section.

With your terminal open, you can install Resources quite easily:

That should add Resources to your application menu. It will fall under the Administration sub-section. I’ve seen some distros not show newly added Flatpaks in the menu until after a reboot. If that’s the case, you can manually run Resources with this command:

Once you open the application, all will be revealed. Here’s an image:

Resources default screen.
This should be self-explanatory if you’ve monitored resources before.

One of the great things is that you can monitor applications that might have multiple processes – such as Google Chrome. You can also monitor processes individually, including closing those applications and processes.

Additionally, you can monitor CPU use, memory use, GPU use, and your various storage devices – including optical media. If you want to know read and write speeds on the fly, that information is available in an easily understood graphical tool.

That’s right… I’m covering a graphical tool today! Let it be said that a GUI is sometimes a good tool for the job and that the Resources application is one of those tools.

If you click on the hamburger menu near the top, you can also adjust your preferences. You can choose to display more information than the default and adjust how you’d like to read things like temperature values. It’s a pretty handy application.

Yes, you already have a GUI tool to monitor system resources but you can opt to use this one instead. It’s a pretty large file (or multiple files) but that’s to be expected with Flatpaks. So, get a coffee going while you wait for the application to install.

Closure:

So, there’s a GUI tool you can use to monitor system resources. It’s worth investigating. Some of you may like it well enough to switch to it entirely. Others may find they reach for it when they need more information than they usually have available on one screen. Either way, it’s a handy application and one worth knowing about.

The Meaning Of “Load Average” On Linux?

You may have come across “Load Average” in your Linux travels. It’s common for it to be misinterpreted but it’s simpler than you might think. In this article, I’ll try to explain it for you.

Knowing the load average may let you know when you need more powerful hardware. It could indicate that there’s a runaway process, or that there has been some sort of hack and you’re now running malware, perhaps mining cryptocurrency in the background. The load average is valuable information, though many folks don’t seem to know what it means.

I also see some load average misconceptions when I travel the ‘net. There are faulty interpretations and faulty implications. For example, it doesn’t necessarily mean that you were hacked or need hardware, it just means you need to start looking into the cause of a high load average. It doesn’t mean definitely anything – it could just be that you had a high load for a while due to a compute-intensive process.

This shouldn’t take very long, or be all that complicated, but we’ll see if I’m able to put it into words. I’ve never tried to put it into words before! Let’s see how that works out.

Linux Load Average:

First, let’s crack open your terminal. Use your keyboard and press CTRL + ALT + T. That should open your default terminal.

With the terminal open, run this simple command:

You should get an output similar to this:

So, let’s explain what’s going on here. 

Those are the average of CPU usage over the last 1 minute, 5 minutes, and 15 minutes. Each 1 is a CPU (or CPU core) that was waiting because it was busy. It was waiting, unable to process data because it was too busy running existing scheduled jobs. So, you can have some pretty high numbers.

Sometimes, you’ll see like a 1.04 as a result and that means that one CPU/core had a high average load over the past minute. The load average isn’t what the score was at 1, 5, or 15 minute intervals. It’s an average of CPU usage over time. 

If you have an 8 core CPU and they’re all busy over a minute, you’ll end up with a load average of 8.x, and you may still have a functioning (perhaps slowed down) computer. At the same time, if you’re on an old dual-core CPU then you may find that 2.x means your computer is entirely unusable due to the lag.

Obviously, most folks are going to want a lower load average but some folks may want a higher average so that they know they’re getting the most out of their hardware. As a general rule, you want your CPU’s load average lower so that you can move data in and out of it quickly. Having a high CPU load can create a bottleneck and that’s less than optimal.

Closure:

There we go… I think I explained it well enough. If not, just let me know and I’ll try to answer any comments that are questions. If you can think of a better way to describe it, feel free to add that too! Either way, it’s another article for the archives. Pretty soon, the year will be over!
